If you have a good antenna do you _want_ to use a coil that's going to pick
up fields? I would think you'd want to control the energy getting into your
set.

What ever happened to buying a bottle of fancy whiskey and using the
cardboard tube it came in for a coil?

Yep. Went right past me without even a whoosh noise. ;-)
